They did patch gcc to add some Apple-specific things.  In this case
they taught it to recognize CFStringRef as a string argument suitable
for use with the __attribute__((format_arg(A))) attribute, but gccxml
will only recognize "char*" arguments.

Try creating a "CoreFoundation/CFString.h" header in your own custom
include directory, with this content:

  #include_next <CoreFoundation/CFString.h>
  #ifdef __GCCXML__
  #undef CF_FORMAT_ARGUMENT
  #define CF_FORMAT_ARGUMENT(A)
  #endif
